We look at the division of 21988853 by 25 
We want to divide 21988853 by 25.

Advancing to step 1:
When dividing 2 by 25, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 25

Advancing to step 2:
The number 25 fits into 21 0 times, leaving a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Include the next digit (9) from the dividend after 21, then repeat: 219 / 25

Going ahead to step 3:
When dividing 219 by 25, we get 8 with a remainder of 19.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 200 from 219 to get 19.
Grab the next digit (8) from the dividend, add it to 19, then carry on: 198 / 25

On to step 4:
25 can be fit into 198 7 times, resulting in a remainder of 23.
Record the quotient 7 as the next digit in the result. 
Result so far: 87.0
If we subtract 175 from 198, we get 23.
Fetch the next digit (8) from the dividend, attach it to 23 and continue: 238 / 25

Step 5:
25 goes into 238 9 times with a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 879.0
Subtract 225 from 238 to get 13.
Bring next digit (8) of the dividend behind the 13 and repeat the process: 138 / 25

Step 6:
25 goes into 138 5 times with a remainder of 13.
The next digit of our result is 5. 
Result so far: 8795.0
Subtracting 125 from 138 leaves us with 13.
Fetch the next digit (5) from the dividend, attach it to 13 and continue: 135 / 25

Advancing to step 7:
If we divide 135 by 25, we get 5 and a remainder of 10.
The next digit of our result is 5. 
Result so far: 87955.0
Subtract 125 from 135 to get 10.
Include the next digit (3) from the dividend after 10, then repeat: 103 / 25

Step 8:
103 divided by 25 is 4 with a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 879554.0
The remainder is 3 after subtracting 100 from 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 9:
If we divide 30 by 25, we get 1 and a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 879554.1
If we subtract 25 from 30, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 10:
25 goes into 50 2 times with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 879554.12
Deduct 50 from 50 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
0 divided by 25 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 879554.12
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 12:
The number 25 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 879554.12
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 879554.12 with a remainder of 0.0.
